ATI/Intel setup and vga_switcheroo not working

Hi guys, I'm having a tough time trying to make my Radeon HD6490m work with my current (Radeon / Intel HD3000) setup. I've followed this guide to enable the discrete graphics card:

  1. Installed xf86-video-ati and xf86-video-intel

  2. Blacklisted radeon module

  3. Enabled radeon module at startup with rc.local

However, my Radeon is still not being used, as confirmed by:

$ cat /sys/kernel/debug/vgaswitcheroo/switch 
0:IGD:+:Pwr:0000:00:02.0
1:DIS: :Pwr:0000:01:00.0

and by the Xorg log (it's quite huge, and I don't think it's worth posting it, but feel free to ask if necessary).

So I tried to use vga_switcheroo at startup (via rc.local), to explicitly enable the discrete graphics card:

#!/bin/bash
#
# /etc/rc.local: Local multi-user start-up script.
#

modprobe radeon
echo "DDIS" > /sys/kernel/debug/vgaswitcheroo/switch

but the result is that the boot sequence hangs just after having started all the deamons listed in rc.conf, leaving me with a hard shutdown as the only possibility.

This is the /var/log/everything.log section from the first time the radeon module is mentioned, to the point where the i915 module is disabled:

Re: ATI/Intel setup and vga_switcheroo not working

I have had the same problem.  I'm able to reproduce the problem after boot by:

$ echo ON > /sys/kernel/debug/vgaswitcheroo/switch
$ echo DDIS > /sys/kernel/debug/vgaswitcheroo/switch
$ echo OFF > /sys/kernel/debug/vgaswitcheroo/switch

Then, because I use gnome:

# /etc/rc.d/gdm restart

At this point, the system hangs.  A console login pops up that does not accept any input (and the cursor does not blink).

I'm not quite sure of what log I should look in to find any necessary information, but I can give you my hardware:

$ lspci -k

Re: ATI/Intel setup and vga_switcheroo not working

The way it works for me is switching to tty1, logging in as root and doing it step by step:

systemctl stop gdm
echo DIS > /sys/kernel/debug/vgaswitcheroo/switch
systemctl start gdm; logout

Maybe this is a hint where the problem may come from: After stopping gdm, it often needs several times until the switch is done. Several times client refused switch, then in the 3rd or 4th try i915: switched off. I don't know the difference between DIS and DDIS by the way, is the 2nd D for delayed? I wonder why after stopping gdm, the system seems to take a lot of time until realizing the IGD isn't in use anymore. Any help appreciated, I would love a solution that allows switching from the desktop without using the tty. Even a reliable script would be better. My components, by the way:

00:02.0 VGA compatible controller: Intel Corporation Core Processor Integrated Graphics Controller (rev 18)
    Subsystem: Acer Incorporated [ALI] Device 0359
    Kernel driver in use: i915

01:00.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI Manhattan [Mobility Radeon HD 5400 Series] (rev ff)
    Kernel driver in use: radeon

Re: ATI/Intel setup and vga_switcheroo not working

DDIS simply means wait until X restarts.

I just attempted to switch from tty1, but the issue persists: the system hangs when it activates the radeon card.  I waited for about ten minutes before sending a ctrl+alt+del.

I catted the output of 'echo DIS > /.../switch' into a file (because the screen hangs) and it has no output.

Re: ATI/Intel setup and vga_switcheroo not working

When I was on the IGD, I echoed DDIS to switch and logged out. After the immediate gdm restart, the laptop correctly used the radeon card. The other way around (echoing DIGD and quitting the session) did not work on the other hand, gdm did not start, and since I had a black screen with a non-blinking cursor, I supposed my laptop crashed. In fact, it had not, and I could switch to tty1, but had to wait about 15 seconds before switching to IGD was accepted (before, i had to stop gdm again because it seemed to hang in some kind of undefined state). Dmesg isn't very helpful either. Weird.

Any ideas?

Re: ATI/Intel setup and vga_switcheroo not working

Hi, tl;dr, just the topic.
I own a hybrid video laptop featuring a Intel/ATi combo, Intel being the power saving video card and ATi the high performance card; so far I was able to switch forth and back and use any of both GPU at will however with some constraints:
a) I can use either of them one at a time.
b) I need to log out, kill X, do some tweak in order to maximize graphic card performance and then start X again.
So far I allways did this with the old initscripts system so please note that there might be a difference with new systemd - since I use Intel's GPU most of the time I didn't used the ATi GPU since I switched to systemd, you're warned smile

Now, these are my config files that enable the use of both cards:

/etc/mkinitcpio.conf

~ $ head /etc/mkinitcpio.conf 
# vim:set ft=sh
# MODULES
# The following modules are loaded before any boot hooks are
# run.  Advanced users may wish to specify all system modules
# in this array.  For instance:
#     MODULES="piix ide_disk reiserfs"
MODULES="radeon i915"

- Intel GPU optimized files -
/etc/tmpfiles/optimized.conf

~ $ cat /etc/tmpfiles.d/optimized.conf 
w /sys/kernel/debug/vgaswitcheroo/switch - - - - OFF

#w /sys/class/drm/card0/device/power_profile - - - - low
w /sys/class/drm/card0/device/power_method - - - - dynpm

#w /sys/module/snd_hda_intel/parameters/power_save - - - - 1

w /sys/kernel/mm/transparent_hugepage/enabled - - - - madvise
w /sys/kernel/mm/transparent_hugepage/defrag - - - - madvise
w /sys/kernel/mm/transparent_hugepage/khugepaged/defrag - - - - 0

w /proc/sys/kernel/watchdog - - - - 0
w /sys/class/scsi_host/host[0-5]/link_power_management_policy - - - - min_power
w /sys/bus/pci/devices/*/power/control - - - - auto

w /proc/sys/vm/dirty_writeback_centisecs - - - - 1500

As you will note, I configured a default setup to use the Intel GPU and completely turn off the ATi GPU.
Now, this is my /etc/X11/xorg.conf. Please note that it includes a series of tweaks and optimizations I found over time that works pretty well with most newer Intel and ATi GPUs.

Then, to switch to the ATi card I do this:
1. /etc/X11 # echo DIS >> /sys/kernel/debug/vgaswitcheroo/switch  [this will turn the discrete card on]
2. cp xorg.conf.ATi_enabled xorg.conf
and I'm ready to launch X again using the discrete card. Note that I copy a ATi-enabled xorg.conf over the Intel-enabled xorg.conf (and backwards!) to avoid editing the xorg.conf file everytime I want to switch the VGA cards.

Last, this additional kernel-line flags will help you get out the most of your battery: rootfstype=ext4 hpet=force i915.i915_enable_rc6=1 pcie_aspm=force i915.lvds_downclock=1 radeon.pcie_gen2=1 i915.semaphores=1 security=tomoyo resume=/dev/sda3 acpi_backlight=vendor i915.modeset=1 usbcore.autosuspend=1 radeon.agpmode=-1 ipv6.disable=1 apparmor=0 nmi_watchdog=0 libahci.ignore_sss=1 elevator=bfs
(use what applies to your case)

Be sure to follow the wiki and to install both intel-dri and ati-dri packages.
